Digital Memosens sensors: with its good galvanic isolation the Memosens prevents interferences, allowing straightforward and safe measurements even with most difficult potentials. The sensors can be easily handled under adverse conditions - you can even connect them under water.

Most versatile hazardous and safe-area applications, such as in industry, in the lab, for environmental protection, food processing, as well as water or waste-water treatment.

The world's only portable device for liquid analysis with ATEX approval for measurements up to zone 0/1. Ideal for applications in the process industry. Direct on-site testing of process measuring points. It is compatible with all Memosens process sensors. Memosens sensors with different parameters can be checked without changing the sensor cable. The MemoLog function allows the user to log calibration data from various Memosens measuring points, which can then be easily transferred to a computer via the standard USB connection. The Paraly SW 112 software enables user-friendly management of all recorded data.
  • Micro USB port and Paraly SW 112 software.
  • The mineral glass display is perfectly readable even after years.
  • Application in hazardous locations for measurements up to Zone 0/1.
  • Portable device for liquid analysis in hazardous locations.

The data logger:
The meter provides a data logger. Prior to use, it must be configured and then activated. The following logging types can be selected:
  • Manual logging by pressing the softkey.
  • Time-controlled logging at a fixed interval.
  • Signal-controlled logging of measured value and temperature.
  • Combined time- and signal-controlled logging.

The data logger records up to 5000 entries, which can be assigned to different measuring points (TAGs) and annotations.
